Syntax

C++

public ref class SqlContext sealed

Properties

	Name	Description
	IsAvailable	Specifies whether the calling code is running within SQL Server, and if the context connection can be accessed.
	Pipe	Gets the pipe object that allows the caller to send result sets, messages, and the results of executing commands back to the client.
	TriggerContext	Gets the trigger context used to provide the caller with information about what caused the trigger to fire, and a map of the columns that were updated.
	WindowsIdentity	The Microsoft Windows identity of the caller.

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

The SqlContext object can be used to obtain the trigger context (for code executing in a trigger) and the pipe object (when available, such as in stored procedures). It can also be used to obtain a WindowsIdentity object that represents the Microsoft Windows identity of the calling client, if the client authenticated with the server using integrated authentication.

Examples

The following example creates a new SqlDataRecord and its SqlMetaData. The example then marks the beginning of a result set using the SendResultsStart method, sends records with example data back to the client using the M:Microsoft.SqlServer.Server.SqlPipe.SendResultsRow method, and marks the end of the result set with the SendResultsEnd method.
